.- The radioactivity emitted by the Fukushima nuclear plant in northeastern Japan again today to exceed the legal limit the damage caused by the devastating earthquake on Friday, Kyodo news agency reported. Since the earthquake and tsunami, governments work against the clock to address the overheating of several reactors the cooling system failure, amid fears that a merger of the core.
The situation is unclear since Saturday, an explosion occurred at the Fukushima plant 1, trying to lower the temperature of boiling reactors 1 and 3. Japan government spokesman Yukio Edan, acknowledged yesterday the possibility of another explosion in the secondary containment vessel of the reactor 3 by the accumulation of hydrogen, but not cause serious damage.
It is trying to inject salt water to cool the turbine and prevent a disaster, while the authorities insist that there is no data to confirm a core meltdown process, only one possible "distortion" of it. The lack of information generated great concern last night and some media speculated even the possibility that a possible radioactive leak came to Tokyo, something that most experts have agreed to reject.
According to the Executive, the highest level recorded ionization microsievert 1.557 yesterday, to about the 500 considered desirable for health-equivalent of three radiographs of the stomach. A total of 180 000 residents have been evacuated in a security perimeter of 20 km around the plant, at least 37 people have been exposed to radioactivity, NHK television reported.
All nuclear plants in areas affected by the earthquake of magnitude 9 on the Richter scale and tsunami have been stopped on Friday.
